STM32 NUCLEO64: PWM has no output

I'm using STM32F303 NUCLEO64. I used CubeIDE to auto generate the code. The program is running Coz I can see the printf() is updating via SWO. I have added 1 sec delay after GPIO and TIM3 initalization. And I have started PWM by using this…

Can STM32F303 on-chip I2C be used, to connect to STM32F3DISCOVERY on-board gyroscope (I3G4250D or L3GD20)?

The STM32F3DISCOVERY board has an STM32F303VC microcontroller, which has built-in SPI and I2C support, and a gyroscope which supports both SPI and I2C. Per the board's user manual and schematic, the gyroscope is connected to the microcontroller's…

Setting registers using embedded rust

So... I've been following the embedded rust book... and I'm currently reading about registers. Now, the book does suggest that I use an STM32F303VC discovery to avoid issues, but I couldn't find one, due to which I got a Nucleo F303RE instead. the…

How to properly configure an stm32 with lmt86?

I'm implementing an stm32 which reads data from an LTM86 sensor and transmits the converted temperature in a CAN bus. My problem is related to the ADC configuration because the voltage value provided by the ADC is different from that measured on the…

STM32 SPI Data Packing

I can't get the SPI on my STM32f3 discovery board (Datasheet) to work with gyroscope sensor (I3G4250D) on the register level. I know I'm sending data since I'm in full duplex and receiving dummy bytes from sensor using 16 bit data packing but when…

STM32 I2C Only Transmits Once

I'm using stm32f3 Datasheet as reference for register level programming instead of HAL. I'm pretty sure I set up everything correctly since I am actually able to transmit bytes of data through I2C peripheral however it fails to send a byte when I…

How to do a adc conversion every 1us with Nucleo-F303K8?

Im using the STM32 Cube IDE. What I tried now is enable MSM in TIM2 and output_compare_no_output on Channel 1 and select "Reset" as the Trigger Event. Then I went to ADC1 and enabled Regular_Conversion_Mode, set Number_Of_Conversions to 1 and the…

STM32: simple SPI transfer

I am working with a STM32F3DISCOVERY board and I'm trying to dive a bit deeper into the abstractions of the HAL. I made a simple version of a function that transmits data over SPI, sadly it does not work (at least the DAC I'm sending it to does not…
